To all whom it may concern:

Be it known that I, RoY W. IDE, a citizen of the United States, .residing at Springfield, in the county of Sangamon and State of Illinois, have invented a certain new and useful Improvement in Illuminating Systems, of .which the following is a full, clear concise, and exact description. kl

My invention relates to motion transmitting apparatus in some of its aspects and to an illuminating system employing such apparatus in other aspects of the invention.

The invention has for its broad purpose the provision of mechanism whereby a motor may be selectively coupled with wheels provided with controlling agencies limiting them to rotations which differ in extent. That is, the motor is enabled to operate one wheel throughout one range and another wheel throughout a different range, by the apparatus of the invention. Such apparatus may have different employments,

the important one being to vary the time 7, be lighted. The invention,

that a lamp maIy when thus emp oyed, is of particular service in photographic development, although the invention is not to be limited to such use.

I will explain my invention fully by reference to the acom'panying drawing in which Figure 1 is a perspective view of so much thereof as'is necessary to an understanding of the invention, some circuit connections being diagrammatically. indicated --in this figure; Fig. 2 is a sectional view on line 22 of Fig. 3; and Fig. 3 is a sectional view on line 3-3 of Fig. 2.

Like parts are indicated by similarcharacters of reference throughout the different figures.

The drawing exhibits an illuminating system which includes a circuit 1, 2 for conveying current to an electric lamp 3 which is bridged across the sides of the circuit. The motor iwhich -I emplo is also preferably electrically operated. it is connected between the sides 1 and 2 of the circuit in order .to be supplied with operating current from said circuit. A rheostat 5 is included in one of the motor connections whereby the speed of the motor may be varied. A switch 6 is serially included in the lamp circuit, the switch being self-opening so that the lamp will not furnish switch is actuated.

The motor 4 drives a shaft 7 either directly illumination unless the the teeth. Thus the or through the intermediation of suitable,

speed reducing gearing 8 if the motor happens to be an electric motor. A plurality of toothed Wheels'9, 10, 11 are shaft. The teeth upon each wheel are spaced loose upon the farther apart or closer together than the teeth upon each of the other wheelsf Collars 12, 13, 14 are fixed upon the shaft to turn therewith. Springs 15 serve to press the wheels toward the collars, there being one collar individual to each wheel. Friction washers or collars 16 are disposed between the aforesaid collars and the Wheels. The

springs press the wheels against the collars I 16 so that when the wheels are released from the detaining mechanism hereinafter to be described they will rotate with the shaft. Individually operable detents 17, 18 and 19 are respectivel individual to the wheels 9, l0 and 11. 'l hese detents are preferably mounted to turn at their intermediate portions upon a rod 20 common to the detents.-

The forward ends of the detents are receivable in the notches between the teeth upon the wheels and the rear ends of the detents are upwardly pressed by leaf springs 21 so that when the forward ends of the detents are in registry with the spacesbetween the in parallelism with the shaft 7. When anybutton 1, 2 or 3 is depressed the detent corresponding theretois raised at its forward end whereupon the wheel normally restrained by this detent is permitted to turn a space corresponding to the width of the wheel tooth that rides over the detent, the forward'end of the selected detent dropping into the ensuing notch in the wheel. The wheel 9 is limited to turn through a shorter arc than the wheel 10 which, in its turn, moves through a shorter distance than the wheel 11. The wheel 11 has longer slots between its By depressing teeth than do other wheels so that this wheel will continue to turn even after the forward end of its detent drops into a space between shaft 7 may be effective throughout one angle or another or the third,

remaining in circuit only as long as the forward end of the selected detent rides upon the crown of the ensuing tooth of the wheel having such detent. The crowns of the teeth of each wheel are of different lengths from the crowns of the teeth of the other wheels wherefore the duration of engagement of the bar 23 with the switch 6 varies according to the toothed wheel which has been released to cause corresponding variation in the duration of the illumination of the lamp.

If the equipment is employed in photography the wheels 9, 10 and 11 may, for example, respectively turn for one second, two seconds, and three seconds tocause the lamp to glow one second, two seconds or three seconds. If the fluid employed in the photographic operation becomes weaker, I reduce the speed of the motor, as for example with the aid of the rheostat, to compensate forv the reduced strength of the fluid.

While I have herein shown and particu larly described the preferred embodimentof my invention 1 do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, but having thus described my invention 1 claim as new and desire to secure by Letters Patent the following 1.
